This beautiful little “Flirt” transistor radio from 1970 has had a loving internet radio conversion using a Raspberry Pi Zero. All the original controls have been re-used and with its LiPo battery & LED VU meter it’s ready to bang out tunes in the bathroom.
This could be one of my favourite projects ever, it has just the right combination of Old Tech and New Spec, and was my quickest to date, providing music in the bathroom just a week after I picked it up at the car boot.
As ever I learned new things while building it, including re-using parts of the volume dial to make microswitches that look identical to the original controls – definitely a technique I’ll be using in future projects.
I also used a LiPo battery for the first time in this build, something I’ve been shy of in the past, and was pleasantly surprised with the resulting flexibility and impressive run-time. Using a combination of the Pimoroni LiPo Shim and an Adafruit Micro LiPo I was able to integrate the charging circuit into the build itself, pleasingly tucked away under the original battery lid.
This Cheetah 125 joystick from the 1980s has had a full rebuild with shiny new microswitches, arcade buttons and a Pimoroni Player X controller board. It now has four independent buttons and connects via USB, ready for some serious RetroPie gaming action.
We had great fun converting this old joystick to work on RetroPie – it really brought back the glory days of “gaming” on my old Commodore Vic 20, I had exactly the same model when it was new.
The build wasn’t without surprises though, I’d forgotten that in the 80s all buttons performed the same function – four in this case all wired together! With the help of a Player X board from Pimoroni we were able to make each button independent, and added in a couple of extras to make RetroPie play easier.
The idea behind the joystick conversion was to provide Player 2 controls for the Pi Tourer Game Console, and it’s now added all the blood-pumping fun of head-to-head competition to our retro gaming, with predictable gloating from the younger members of the household!
This 1963 Ever Ready car radio now has a new life playing RetroPie games!
It has a Raspberry Pi 3 and Picade controller inside, as well as a Pimoroni Blinkt that makes the front panel glow brightly in a range of colours, depending on what emulator is playing.
The fun doesn’t stop there though, thanks to its inbuilt handle and easy docking ports the Pi Tourer can be carried to other rooms, friends’ houses or anywhere a spare HDMI port can be found.
I couldn’t resist this 1963 radio at the car boot earlier in the year – it cost a princely £4. It was obviously not your normal car stereo however, as the underside had its own inbuilt speaker.
Research showed it had been a dual-purpose device, so you could remove it from your car and use it just like a normal portable radio. I decided to recreate this function, making it so it could “dock” with the workbench but still be easily removed and carried around to other retro gaming locations.
This project was as much fun to build as it is to play with, you can read the full story on Instructables and Hackster. The code I used to control the Blinkt colours based on the RetroPie emulator selection is all documented on GitHub.
For once this project turned out exactly as planned, there was just enough space in the case and I didn’t have to compromise on features. There’s one thing missing though – controls for Player 2! RetroPie is a ton of fun but playing against the kids takes it to another level altogether, apart from when they beat me, which is most of the time. For the next project we’re going to be building a controller for Player 2, upgrading an original 80s joystick and making it RetroPie-Ready.
Stay tuned for updates on that and be sure to subscribe on YouTube to catch the video when it’s released, probably around the 1st of September.
You can get downloadable .pdf versions at the links above, but we just love the browsability of the printed magazines.
The MagPi has a great feature on the shiny new Raspberry Pi 4, lots of excitement about that here and hopefully a “monster” themed build using a Pi 4 4GB coming from us in the Autumn.
HackSpace is holding its own in the coffee table stakes though, the article on re-purposing aluminium cans went down especially well. Maybe because they’re so readily available in this household? Who knows.
This iconic digital clock from the 1970s now has a new life stylishly displaying YouTube statistics. It’s powered by a Raspberry Pi Zero and harnesses a simple Python script to retrieve Subscriber and View numbers for the Old Tech. New Spec. channel from the YouTube Data API, displaying the results on a Pimoroni Inky pHAT display.
The clock’s original alarm on/off switch now toggles the e-ink display between Views and Subscribers, and an inbuilt LED glows up the translucent red plastic around the display as it updates.
It’s a fun & practical addition to my office, sitting quietly on my desk speaker, and seeing the stats slowly increase helps keep me motivated to make more projects and videos. It also won First Prize in the recent Instructables Internet of Things Contest!
I bought this clock a year or two back, bundled with an old robot toy, and it was in daily use until it went pop recently – when it joined the ranks of broken Old Tech in the workshop awaiting conversion. The build was straightforward and involved a lot of precise measuring, as well as my favourite Raspberry Pi companion, Lego bricks!
I’m really pleased with the result and it’s a lovely looking little thing – nice coverage on the Hackster Blog too!
The PiNG Video Doorbell is powered by a Raspberry Pi and is retro-stylishly cased in a 1986 Intercom and an old Sony cassette player.
When the doorbell button is pressed the Pi makes a high-quality video call using Google Duo, which can be answered on a phone, tablet or computer, letting you see and speak to callers when you’re away from home (or at home but trapped under a cat). It works over WiFi and cellular, so you can even answer the door when you’re out pounding the streets.
It also sounds a standard wireless door chime inside the house as a fail-safe, in case the call can’t be taken.
The doorbell unit is fitted outside the house, with a companion base unit inside, connected with 6-core alarm cable. The base unit houses a Pi 3B+ and is housed in a stripped-out cassette player.
It works amazingly well and the Google Duo sound and video is smooth – I took a call from a delivery person while out walking yesterday lunchtime which was very exciting!
I started this project in early March and finished it at the Easter weekend, and it’s been an absolute barrel of fun, I’d highly recommend playing around with Google Duo on a Raspberry Pi! If you have a Pi and some bits lying around you can probably make something similar in a couple of hours.
There are full project write-ups with instructions, photos and code at the links below:
The workshop has embraced the Spring thaw, the office is freshly renovated and now I’m elbow-deep in a brand new Raspberry Pi project, hoping to release the YouTube video & detailed write-ups on Instructables and Hackster in the next couple of weeks if all goes well. I’ve really missed the smell of solder and melted plastic over the winter months.
I’m keeping a lid on the exact details for now, but as Wallace said in The Wrong Trousers it’s hopefully going to be a “valuable addition to our modern lifestyle”.
It’s a pretty straightforward build, with easily modified Python code, some moderate hardware hacking, and more than a sprinkle of Google.
Stay tuned for further updates and more teaser photos!
I picked up an official Pi Zero case at the Pi Store last week and only opened it yesterday – I’m notoriously easily pleased but was thrilled to find there were three different case tops included! Plus, as icing on the cake, a tiny cable to connect a Pi camera module tidily inside one of the lids.
As luck would have it I already had a Pi Zero W handy and set up with MotionEye so it took minutes to clip the whole thing into place. I’ve been looking for a nice security camera case for a while and this ticked all of the boxes at once.
I tried it on the dining room wall but the field of vision didn’t cover the whole room – something that was rectified by a £5 set of smartphone lenses from Tiger – the set came with a fisheye and “diamond” lens but the Wide Angle one was perfect for the job. While there I also picked up a 3 metre white USB cable for £3, which let me mount the camera high up in the room.
The lens was easily superglued to the case, and I made a bracket out of Lego to hold it at just the right angle near the slope of the ceiling. The case was fixed to the bracket using 3m self-adhesive velcro pads (on special this week at Lidl)
To finish the job I tidied the cable with some thin self-adhesive conduit, which is mostly tucked away behind a curtain. I’m so pleased with the end result, it only took about a half-hour to put everything together and it looks really clean and subtle on the wall. Now I can keep an eye on the cats without needing them to wander right in front of the camera!
This was also a great first experiment with camera lenses – my next big Pi project is camera “focussed” and we’ll be using the wide angle lens again as part of the build. Maybe not a pink one this time though.
Very excited to have a project featured in the MagPi this month, it’s a vintage Hitachi television I converted last year. It displays digital TV from another Raspberry Pi running a TV HAT, and uses the original rotary tuning dial to change channels.
As you can see hard copies are available in shops as well as the pdf version online. It’s a great issue all round and I’ve already been inspired to grab some arcade joysticks and buttons to try out some of the tutorials.
The article covers my experiences using the TV Hat with a converted TV from the 1970s – the original TV build Instructable write-up is here and the more recent TV Hat version is here. The simple Python script used to change the channels is available on GitHub.
There’s also a YouTube video of the unboxing and setup of the TV Hat…
…and one that gives a bit more information about how the Hitachi Pi TV was converted.
I’ve always been fascinated by televisions, as evidenced by the photo they included of me unboxing my first TV, aged around 10.
